The invention discloses a three-river parallel flow water frying power generation flood control protection method which comprises the steps of horizontal tunnel arrangement, water diversion pipe step arrangement, ventilation window arrangement, water frying tunnel water pipe V and water tank comparison, tunnel section change, river channel centrifugal sand discharge and linear river channel sand discharge. The method comprises the following steps: arranging a sand blocking semi-water gate, comparing tunnel segmentation conditions, arranging a water inlet sand discharge pump-floating platform, and arranging a water conduit funnel, a screen and a hexagonal filter screen. The hydroelectric generation is stable in benefit; rivers are networked, and the drought and flood adjusting capacity is multiplied and far exceeds that of a water storage power station; three gorges have more time to raise the water level of the reservoir, more electricity is generated, and flood is prevented by lowering the water level; if the three gorges are attacked to break the dam, the destructive power of the flood to the downstream is reduced, namely, the attacked value of the three gorges is reduced, and the risk of being attacked is also reduced; for flood disasters, downstream flood control is helped, red envelopes can be collected, and water is most suitable for being used as the red envelopes in rainy seasons; the three gorges dam break exercise is facilitated, and controllability is achieved.

The utility model relates to the technical field of assembly type building construction, concretely is a kind of assembly type building wall body anti-seismic connecting node structure, including pedestal and the L-shaped structure on the pedestal, and the L-shaped structure is connected with the damper between the pedestal;The bottom end of the pedestal is provided with embedded part, the L-shaped structure includes horizontal L-shaped plate and vertical L-shaped plate that is vertically arranged on the horizontal L-shaped plate;The vertical L-shaped plate includes two fixed plates connected in right angle, the outside of two the fixed plate is respectively fixed with assembly box, each the fixed plate is all provided with the threaded hole that is connected with the inside of assembly box, threaded column is arranged on the threaded hole, and the threaded column is located on the end in the inside of assembly box and is equipped with handle and gear, the inside of assembly box is also provided with lifting plate, locking mechanism, damping spring and guide mechanism. Through the energy dissipation effect of damper, wall body can consume energy by displacement and deformation in earthquake, rather than directly transmitting rigid impact.

The present application relates to a multiphase water self-sealing multi-pivot joint anti-explosion device, belonging to the technical field of anti-explosion devices, and is used to solve the technical problems of poor anti-explosion effect and low safety of anti-explosion devices. The anti-explosion device includes: an explosion-proof housing, a connecting pipeline, a first gravity airtight valve, and a first airtight valve gravity hammer. The explosion-proof housing is of a cylindrical structure, and the explosion-proof housing is suitable for containing water; the connecting pipeline includes: an air flow channel, a first opening and a second opening communicated with the air flow channel. The first opening is suitable for communicating with an explosive fluid, the second opening is communicated with the explosion-proof housing, and the second opening is located below the water level; the first gravity airtight valve has a first state and a second state. In the first state, the first gravity airtight valve can be closed under the gravity of the first airtight valve gravity hammer to disconnect the first opening from the second opening. In the second state, the first gravity airtight valve can be opened under the action of the air explosion airflow to connect the first opening with the second opening.

The utility model relates to the technical field of protective net, especially to a debris flow protective net device, including the pre -buried board setting is rectangular board body structure, both sides of pre -buried board top intermediate position all fixedly installed are stand, the annular groove is seted up on the stand, the buffer mechanism is sleeved in the annular groove, the first protective net is arranged between two stand, the steel cable is fixedly connected with the side of first protective net, and the steel cable is inserted in the buffer mechanism, the U type protection pole is horizontally arranged behind first protective net, and both ends of protection pole are fixedly connected in the inside of two stand, and the second protective net is vertically laid on the protection pole, the utility model has the beneficial effect that can protect first protective net in the moment of the impact of debris flow to first protective net, and can improve the interception effect to debris flow with the cooperation of second protective net.

This utility model relates to a three-layer foundation for preventing wax moth infestation, comprising a three-layer foundation structure including an upper foundation wax structure, a lower foundation wax structure, and a middle protective structure incorporating a drug that restricts wax moth survival. The upper foundation wax structure is disposed on the upper surface of the middle protective structure, and the lower foundation wax structure is disposed on the lower surface. Both the upper and lower foundation wax structures have concave and densely packed hexagonal honeycomb cells, with the bottom of each hexagonal honeycomb cell forming a Y-shaped structure. This utility model increases the resilience of the honeycomb and simultaneously exerts a certain degree of toxicity and restriction on the reproduction and growth of wax moths.
